As I can't find anything related to the world generation in Google (most of results are Minecraft-related) I have to ask few questions about world generation there:
1. What algorithms should I use to make 2d "world" map? (based on seed and world creation parameters)
2. Is it possible to make 3d map using the same seed, world creation parameters and data from world map without generating the whole map at start (generation after player will choose site, not during initial generation)? Each "chunk" must always look the same and seamlessly connect with another chunks regardless of choosen world chunks. Player can choose any chunks amount, like 1X1, 2X1, 3X2, 5X5. Little example below:
3. I want to add minerals into 3d map rocks - is it possible using specific algorithm (again, generation depending on seed and parameters - map using the same seed and parameters must be always the same)?
Thank you in advance for all replies.
